Manduka's AligN yoga strap combines the traditional strap design of the legendary BKS Iyengar. Made with unbleached natural cotton webbing and an innovative sure-secure interlocking buckle, this AligN yoga strap will support and enhance your practice. Yoga straps are a great addition to any practice! Providing extra length so you can reach further and stretch deeper, straps are a helpful tool for yogis of all levels. If you're using a strap to lengthen your reach for stretches that are just a bit too tight, the shorter length should suit you. If you're doing a restorative practice, the longer strap will give you more options.
